The OpenSSL libraries will ensure that they do. +.PP +The primary responsibility of the SKEYMGMT operation is to hold the +provider side key data for the OpenSSL library EVP_SKEY structure. +.PP +All "functions" mentioned here are passed as function pointers between +\&\fIlibcrypto\fR and the provider in \fBOSSL_DISPATCH\fR\|(3) arrays via +\&\fBOSSL_ALGORITHM\fR\|(3) arrays that are returned by the provider\*(Aqs +\&\fBprovider_query_operation()\fR function +(see "Provider Functions" in \fBprovider\-base\fR\|(7)). +.PP +All these "functions" have a corresponding function type definition +named \fBOSSL_FUNC_{name}_fn\fR, and a helper function to retrieve the +function pointer from a \fBOSSL_DISPATCH\fR\|(3) element named +\&\fBOSSL_FUNC_{name}\fR. +.PP +\&\fBOSSL_DISPATCH\fR\|(3) arrays are indexed by numbers that are provided as +macros in \fBopenssl\-core_dispatch.h\fR\|(7), as follows: +.PP +.Vb 1 +\& OSSL_FUNC_skeymgmt_free OSSL_FUNC_SKEYMGMT_FREE +\& +\& OSSL_FUNC_skeymgmt_import OSSL_FUNC_SKEYMGMT_IMPORT +\& OSSL_FUNC_skeymgmt_export OSSL_FUNC_SKEYMGMT_EXPORT +\& +\& OSSL_FUNC_skeymgmt_generate OSSL_FUNC_SKEYMGMT_GENERATE +\& +\& OSSL_FUNC_skeymgmt_get_key_id OSSL_FUNC_SKEYMGMT_GET_KEY_ID +\& OSSL_FUNC_skeymgmt_imp_settable_params OSSL_FUNC_SKEYMGMT_IMP_SETTABLE_PARAMS +\& OSSL_FUNC_skeymgmt_gen_settable_params OSSL_FUNC_SKEYMGMT_GEN_SETTABLE_PARAMS +.Ve +.PP +The SKEYMGMT management is inspired by KEYMGMT but is simpler. +.SS "Key Objects" +.IX Subsection "Key Objects" +A key object is a collection of data for an symmetric key, and is +represented as \fIkeydata\fR in this manual. +.PP +The exact contents of a key object are defined by the provider, and it +is assumed that different operations in one and the same provider use +the exact same structure to represent this collection of data, so that +for example, a key object that has been created using the SKEYMGMT +interface can be passed as is to other algorithms from the same provider +operations, such as \fBOSSL_FUNC_mac_init_opaque()\fR (see +\&\fBprovider\-mac\fR\|(7)). +.PP +With the export SKEYMGMT function, it\*(Aqs possible to select a specific +subset of data to handle, governed by the bits in a \fIselection\fR +indicator. The bits are: +.IP \fBOSSL_SKEYMGMT_SELECT_SECRET_KEY\fR 4 +.IX Item "OSSL_SKEYMGMT_SELECT_SECRET_KEY" +Indicating that the secret key raw bytes in a key object should be +included. +.IP \fBOSSL_SKEYMGMT_SELECT_PARAMETERS\fR 4 +.IX Item "OSSL_SKEYMGMT_SELECT_PARAMETERS" +Indicating that the parameters in a key object should be +included. +.PP +Combined selector bits are also defined for easier use: +.IP \fBOSSL_SKEYMGMT_SELECT_ALL\fR 4 +.IX Item "OSSL_SKEYMGMT_SELECT_ALL" +Indicating that everything in a key object should be included. +.PP +The exact interpretation of those bits or how they combine is left to +each function where you can specify a selector. +.SS "Destructing Function" +.IX Subsection "Destructing Function" +\&\fBOSSL_FUNC_skeymgmt_free()\fR should free the passed \fIkeydata\fR. +.SS "Key Object Import and Export Functions" +.IX Subsection "Key Object Import and Export Functions" +\&\fBOSSL_FUNC_skeymgmt_import()\fR should import data into \fIkeydata\fR with values +taken from the \fBOSSL_PARAM\fR\|(3) array \fIparams\fR. It allocates the \fIkeydata\fR +object (there is no separate allocation function). +.PP +\&\fBOSSL_FUNC_skeymgmt_imp_settable_params()\fR returns a list of parameters that can +be provided to the \fBOSSL_FUNC_skeymgmt_import()\fR function. +.PP +\&\fBOSSL_FUNC_skeymgmt_export()\fR should extract values indicated by \fIselection\fR +from \fIkeydata\fR, create an \fBOSSL_PARAM\fR\|(3) array with them and call +\&\fIparam_cb\fR with that array as well as the given \fIcbarg\fR. +The passed \fBOSSL_PARAM\fR\|(3) array is transient and is freed upon the return from \fIparam_cb\fR. +.SS "Key Object Generation Functions" +.IX Subsection "Key Object Generation Functions" +\&\fBOSSL_FUNC_skeymgmt_generate()\fR creates a new key according to the values +taken from the \fBOSSL_PARAM\fR\|(3) array \fIparams\fR. It allocates the \fIkeydata\fR +object. +.PP +\&\fBOSSL_FUNC_skeymgmt_gen_settable_params()\fR returns a list of parameters that can +be provided to the \fBOSSL_FUNC_skeymgmt_generate()\fR function. +.SS "Key Object Information functions" +.IX Subsection "Key Object Information functions" +\&\fBOSSL_FUNC_skeymgmt_get_key_id()\fR returns a NUL\-terminated string identifying the +particular key. The returned string will be freed by a call to \fBEVP_SKEY_free()\fR +so callers need to copy it themselves if they want to preserve the value past +the key lifetime. The purpose of this function is providing a printable string +that can help users to access the specific key. The content of this string is +provider\-specific. +.SS "Common Import and Export Parameters" +.IX Subsection "Common Import and Export Parameters" +See \fBOSSL_PARAM\fR\|(3) for further details on the parameters structure. +.PP +Common information parameters currently recognised by built\-in +skeymgmt algorithms are as follows: +.IP """raw\-bytes"" (\fBSKEY_PARAM_RAW_BYTES\fR) <octet string>" 4 +.IX Item """raw-bytes"" (SKEY_PARAM_RAW_BYTES) <octet string>" +The value represents symmetric key as a byte array. +.IP """key\-length"" (\fBSKEY_PARAM_KEY_LENGTH\fR) <integer>" 4 +.IX Item """key-length"" (SKEY_PARAM_KEY_LENGTH) <integer>" +The value is the byte length of the given key. +.SH "RETURN VALUES" +.IX Header "RETURN VALUES" +\&\fBOSSL_FUNC_skeymgmt_import()\fR and \fBOSSL_FUNC_skeymgmt_generate()\fR return a pointer +to an allocated object on success and NULL on error. +.PP +\&\fBOSSL_FUNC_skeymgmt_export()\fR returns 1 for success or 0 on error. +.PP +\&\fBOSSL_FUNC_skeymgmt_get_key_id()\fR returns a pointer to a 0\-terminated string or NULL. +.PP +\&\fBOSSL_FUNC_skeymgmt_gen_settable_params()\fR and \fBOSSL_FUNC_skeymgmt_imp_settable_params()\fR +return references to an array of \fBOSSL_PARAM\fR which can be NULL if there are +no settable parameters. +.SH "SEE ALSO" +.IX Header "SEE ALSO" +\&\fBprovider\fR\|(7), \fBEVP_SKEY\fR\|(3), \fBEVP_KEYMGMT\fR\|(3) +.SH HISTORY +.IX Header "HISTORY" +The SKEYMGMT interface was introduced in OpenSSL 3.5. +.SH COPYRIGHT +.IX Header "COPYRIGHT" +Copyright 2024\-2025 The OpenSSL Project Authors.
